3. Size distrbiution data was measured by a cascade impactor. By using following probability paper a determine whether the distribution is log-normal or not? Explain your answer. b. if it is log normal what is the geometric mean and geometric standard deviation of this particle size distribution Size Range 005 0.5-10 1.0-3.0 3.0-5.0 5.0-10 >10 Mass. 25 125 100 75 30 5 10 1 Op (Particle Diameter, um) 0.1 .01 1 1 99 99.999.99 5 10 20 30 50 70 80 90 95 % of particles less than stated Dp
